Butterflies forever! - Awesome experience for all ages! Highly recommend, then be sure to have lunch next door! Found everything we needed in Viator, and have already recommended their site to others traveling to Europe.

watch out for the 🦋 - Such a beautiful experience and very immersive. only thing to say that if you visit here be so careful when walking around. me and my mum watched the same girl step on two poor little butterflies, obviously it was done unintentionally but she was too invested in taking pictures to watch where she was stepping. it’s especially difficult when the buterrflies are the light brown colour that almost completely blend in. we were extra cautious when we were stepping around and then took pictures and looked around whilst standing still:) just a little note because otherwise these poor butterflies won’t see you coming 🦋🦋🦋 especially in the darker rooftop steps and the little tunnels as they fly in there and are difficult to spot. couldn’t recommend more though, worth every penny 💘

pricy and hot, but worth a visit if you love butterflies - We came during the summer and the heat was pretty awful, especially because the greenhouse makes it even more humid. The price was also pretty high (9€) considering it's not that big and can be visited in 15-20 minutes. However if you love butterflies and nature this visit is a must, as you will be able to see the butterflies up close and they will fly all around you, just a magical experience! I recommend coming in colder months as you will not find the temperature too unbearable, and there will probably be fewer people, allowing you to sit on one of the few benches and enjoy the atmosphere 🦋💐✨

Friendly ! - Many species of butterflies. We really enjoyed the moment! There were enough butterflies, of different species.

Must do experience in vienn - Wow. I was absolutely stunned by the beauty found at the butterfly house. Being able to see all the cocoons of different types of butterflies was a nice touch as well. I saw so many different types of butterflies, flowers, and plants. Only complaint was children touching everything they saw.

amazing! - Everything was beautiful, the only thing downside is that there were a lot of people and it was very hot and humid in there. Nevertheless, the place is a MUST VISIT when you’re in Vienna. I read reviews before going and everyone said that there are not many butterflies but that’s so not true… there are a lot of them and they’re so friendly.

Small greenhouse but nice experience - It is a small greenhouse dating back to the Austro-Hungarian Empire where many butterflies are cared for. It is certainly a great experience, even for the little ones, despite the many tourists (avoid the weekend) and the slightly excessive ticket price (€9.50).

Nice, but too crowded - We had to queue for a while and the butterfly house was very crowded, you were almost pushed through. We were through it after just ten minutes, but then we walked the circular route again because I would have found the €9 entrance fee very steep otherwise. It was beautifully designed with a watercourse, a bridge, statues and lots of plants, but overall it was quite small. There is a similar butterfly house in Luisenpark with more butterflies and wider paths, where you can spend longer. Perhaps they should offer tickets for time slots to avoid overcrowding, similar to the Miniatur Wunderland.

Not recommended - Unfortunately, we cannot give a better rating. The prices are unreasonable. There are butterflies with damaged wings everywhere, which is probably due to the many visitors who feel the need to touch the animals. Since there is no one there to check, it is unlikely to get any better. To attract the animals, there are cheap plastic containers with fruit that are right next to the paths, so that the animals are also at risk there. Overall, unfortunately, not recommended.

Waste of money. Staff unable to deal with disabled customer - Hardly any butterflies. Dying plants. Over in 10 minutes and that's walking slowly. The staff were very unhappy about opening the larger barrier to let me through with my walker. I couldn't get out either. A kind member of the public lifted my frame over the barrier so I could get out.
